FRANK FRANZ, OF BURKE, IDAHO, ASSIGNOR OF ONE-HALF TO EUGENE R. DAY, OF WALLACE, IDAHO.

DECK FOR CONCENTRATING-TABLES.

To all whom 'it may concern:

Be it known that I, FRANK FRANZ, residing at Burke', in the county of Shoshone and State of Idaho, have invented certain new and useful Improvements in Decks for ConcentratingTables, of which the following is a specification.

My invention relates to that class of ore concentrators known as slime concentrators and it primarily has for its object to provide a concentrator table deck or a simple and effective construction whereby the ores may be graded while being separated from the gangue and in which the operation of ore concentrators of the type stated may be rendered more efficient.

In its generic nature my invention provides an improved construction of concentrating table or deck having a plurality of sets of parallel grooves and ribs, the grooves being directed toward suitably arranged outlet slots through which the coarser ores are delivered.

The deck also includes a pair of pans or receptacles and deflector ribs for directing the stream of iiner material to the pans where the finer ores are separated.

The concentrates end of the deck is made adjustable and means are provided forflexing or inclining the concentrates end of the deck with respect to the remaining portion whereby to retard the discharge of the materials through the slots and adjust the movement thereof.

In its more detailed nature the invention also includes those novel details of construction, combination and arrangement of parts, all of which will be irst fully de scribed, then be specifically pointed out in the appended claims, and illustrated in the accompanying drawings, in which:

Figure 1, is a top plan view illustrating the invention. Fig. 2, is a vertical longitudinal section on the line 2 2 of Fig. 1. Fig. 3, is an enlarged detail view of a part of the invention. Fig. 4, is a section on the line 4 4 of Fig. 8. Fig. 5, is a section on the line 5 5 of Fig. 1. Fig. 6, is an en* larged detail sectional view on line 6 6 of Fig. 1. Fig. 7, is an enlarged sectional view on the line 7 7 of Fig. 1. Fig. 8, is a cross section on the line 8 8 of Fig. 1.

Referring now to the accompanying drawings in which like numerals and letters of Specification of Letters Patent.

Serial No. 561,800.

reference indicate like parts in all of the iigures 1 is the supporting frame that carries the bearings 2 for the rock shaft 2a on which the yoke members 3 that support the table 10 are carried. Adjustable links 4 hold the yoke members 3 from lateral movement, while longitudinal movement is imparted to the table from the drive sha-ft 5 through the eccentric link and spring mechanism 7 8-9 (see Fig. 2 of the drawings), the longitudinal movement being regulated by the adjustable member 9.

The mounting of the deck on the frame and the mechanism for imparting longitudinal motion thereto and for adjusting the table laterally to change its plane of location may be the same as that disclosed in my co-pending application filed October 27, 1909, Serial No. 524,854, or similar to that disclosed in the Lampert Patent #641,977 of Jan. 23, 1900, or that disclosed in the VVilfley Patent #719,403 of Jan. 27, 1903, as the mechanism for imparting such longitudinal movement to the deck of the table and for effecting the lateral adjustments per 8e, form no part of my present invention.

The frame 10 that supports the deck 11 is carried by the yokes 3, as before stated, and the deck 11 comprises a flat body having a pair of parallel edges 111 11d and an edge 11b at right angles thereto. At the end opposite the edge 11b the table is bevel cut by an edge 11c so that the infeed side 11a of the deck will be of shorter length than the discharge side 111 and that the bevel edge 11C will be at the tail end of the table.

The concentrates end of the table is hinged along a line 27, as at 27a, so that the tail end may be flexed or tilted upwardly f on such hinge by a screw mechanism 26 shown in detail in Fig. 7 of the drawings.

The deck 11 is covered by a yieldable covering 20 of leather or other suitable material. The bevel cut edge of the deck may be lapped up at 20a against the end wall 11c of the deck as best indicated in Fig. 2 of the drawings.

The table edges 11a 11b 11C may be bound by upwardly projected walls 11 a11 c11, best shown in Figs. 1 and 2 of the drawings. The out-flow side of the table is provided with ribs 12, 16 along the edge.

At the concentrates side of the deck the covering 2() is provided with a plurality of sets of longitudinal grooves 13a-14a-15a- 16?L respectively which are of rack shape in cross section, see Fig. 5, to retard the ore particles from passing toward the outflow side 11d of the table and to further effect the retarding` result the grooves 13a- 14u- 15a-16a of the respect-ive sets farthest from the intake side of the deck are bound by a longitudinal rib 13-14-15-16 respectively, see Figs. 1 and 5 of the drawings, so as to form a break Water, as it were.

17 designates the washing pans or receptacles for the fine ores. These pans are located adjacent to the outflow side of the table and are spaced apart, as shown. Each pan 17 has an open side that is secured at 17a to the table deck, the remaining sides being bound by a rib 17b-1717, a part of which is formed into a spout 17e through which the water passes.

Held parallel to the bevel cut edge 11c of the deck are ribs 18--13a respectively, one for each of the pans 17 the ribs extending from the mouth of the pan at the edge nearest the incoming side of the table toward said incoming side. These ribs 1813a respectively serve as divides for the slime as it flows over the table, causing a part of it to pass to one of the pans 17, anot-her part to pass to the other pans 17 and the remaining part to pass over the ribs or grooves 13a-14P-15a-16a respectively.

Vater boxes 19 are supported over the pans 17 to discharge their contents against the pans and they are supplied from any suitable source through pipes 19b and are furthermore supported by suitable supports 19a.

A water box 22 is located along the bevel cut side 11C of the table and along a part of the intake side 11a, such table being supported in a suitable manner from the frame of the table and supplied with water from a pipe 22C, the boxes 22 having discharge outlets 22a that direct the stream of water on the table in suitable places, as shown in- Figs. 1 and 7 of the drawinvs.

23 designates the inlet box into which the ore carrying slimes are directed from any suitable source and from which they are discharged through apertures 23a into a suitable trap formed by the depressed runway 25 into which the trap plate 24 projects, it being understood that the boxes 22 may be supported by suitable supports 23", as indicated in Fig. 8 of the drawings.

In order to adjust the position of the pans 17 to allow the outflow through the spout 17e to be increased or decreased as desired, the pans 17 have arms 17 f through which a bolt 1711 that is carried by fixed brackets 17 projects, and with which a thumb nut 17 k and springs 17nl coperate. By tightening or loosening the thumb nut 17k the pans 17 may be depressed or lifted accordingly.

the discharge from each of the grooves or riflies of the respective set.

In operation power being applied to the drive shaft 5, from a suitable source, through the belt and pulleys 6, the table 11 is reciprocated from left to right and vice versa, in Fig. 1. Upon admitting the ore bearing slimes to the boxes 23 they pass down through the trap 25 onto the deck of the table. Thus all 'of the mineral matter will be submerged in water before it passes onto the table deck. The table is slightly more elevated at the infeed side than at the outlet side so as to cause the slimes from the boxes 23 to flow toward the side 11d, the longitudinal reciprocation of the table causing the slimes to spread out over the entire table surface. During this action the slimes are automatically graded into fine, medium and coarse streams, the fine stream carrying the light ores passing toward the outcoming side 11b of the table more directly than the other streams so as to work toward the left hand pan in Fig. 1 of the drawings. while the medium grade ore carrying slime stream passes toward the other pan 17 at the right of Fig. 1, the heavier stream passing toward the concentrates end of the table over the grooves or riflles 13a-111a-15a-16a over ribs 13-141. 15-16 in turn. As the stream of coarser material passes over the tailing end of the deck the ores will be separated from the fluids and work toward the respective slots 21 through which they are discharged. I find in practice that the first two sets of grooves or rifiies 13a-14a will eect the sepa-ration of the greater part of the heavier mineral matters which are discharged through the respective slots 21 that coperate with such sets of grooves. The lighter of the heavier stream of minerals will be taken up in turn by the grooves 15a-16a and discharged through their respective slots 21 so that by the time the outflow water reaches the outflow side 11d of the table at the concentrates end adjacent to the rib 16, it wil be practically freed of ore. The medium ore carrying stream passes toward the pan 17 where the ore particles of such stream are permitted to settle or precipitate, the pans being supplied with washing water from the water boxes 17, before described. The fine ore is then washed out through the spouts 17e, while the fine mud and sand will accumulate at the places indicated in Fig. 1 of the drawings.

In practice the deck is maintained almost level, it being only more slightly elevated at the intake side than at the outflow side so that the water stands in a sheet over the entire surface of the deck from the outflow side to the feed box so as to produce but a very sluggish current and give the minerals a considerable opportunity to settle, and the motion of the table Will thereby cause the ore to move toward the respective pans 17 which may be raised or lowered, as desired, the grade of mineral obtained' being governed by the adjustment of the pans 17. Similarly, the grade of mineral separated may be varied by using more or less Wash Water. The mineral which is separated at the pan 17 is of a Very line or mud-like grade, While that separated at the concentrates end of the table is of a heavier variety.

Suitable olif-takes 21a may be provided from the slots 21, as desired.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the complete construction, operation and many advantages of my invention will be readily understood by those skilled in the art to which the same appertains.
